Aqua Hot issues

Has anyone had issues with their AquaHot system?? We have a 2025 Tiffin Phaeton and the AquaHot isn't working. Any recommendations for service centers around Vegas??

On Aqua Hot's website you will find a locator for companies that service their product. Also, I assume your coach is under warranty. You can call Tiffin to see if they can help.

BTW, Aqua Hot will not work if your diesel fuel tank level is below 1/4 or if your boiler cooler liquid is too low. There is a tank reservoir in the Aqua Hot compartment. You will see the cold and hot coolant levels. If it is low, you must use the specified boiler coolant. Do not put anti-freeze in the system. Check your fuses to make sure there is power to the unit.

Good luck on finding out what is wrong.

It took us a while to understand the Aquahot's idiosyncratic logic. Even when it works, you kinda have to work with it.

You can always give our techs a call, we may be able to help you get the Aquahot system going over the phone. We can also certainly help you locate a local Aquahot specialist as well!

What's not working? Does it not operate at all? Do the pumps come on but no heat? Does the boiler briefly fire up then shut down?

The reporter in your model year is pretty advanced with decent troubleshooting capabilities and error reporting.

A lot more detail would really help us help you.

Boiler will not light. We took it to a local AquaHot dealer and they checked things out but couldn't diagnose the issue. Now heading south and will need to find a new service center. I will call Tiffin. Thanks for your response.

Just out of curiosity is it working ok in electric mode? Do you get hot water?

Yes, it does work on electric mode. We have hot water but not heat in the coach. The basement compartments are heated.

Hmmm, even in electric mode the cozy heaters should be throwing some heat.
It won’t be much but they till should come on when the fluid is hot enough unless it really cold and the system can’t keep up.

Can be a handful of different things but if electric works and diesel does not, check for a loose wire on your wiring harness.
